HELP! PHP/MySQL Help Needed SOON...

... WLP's web host is upgrading its MySQL servers from 4.1 to 5.0 or thereabouts. Next week the server that hosts the databases for the WikiWLP and these very boards gets upgraded.
I've tried reading the link they provided to guide me through the upgrade... and it's gibberish to me. It presumes I already have an intimate and detailed knowledge of how SQL databases work... and I don't.
Anyone who can read the following and figure out what actually needs to be DONE:
http://dev.mysql.com/doc/refman/5.0/en/ ... eries.html
... give me a PM, OK? Quickly. Before the boards go boom.
